Abstract

A flexible arch model (FAM) is computed to capture and parameterize the variations of the multiple real dental arches in a training set to reconstruct missing teeth in a patient's dental anatomy. Building the FAM includes acquiring multiple sets of digitized dental arches with a pair of maxillary (upper) and mandibular (lower) jaws in the right relative position and gathering a pre-defined set of landmark points on the occlusal surface of each arch all in the same order and same corresponding positions across multiple samples. The gathered vectors of landmark points are used to perform statistical modeling (e.g. Principal Component Analysis) to create a linear subspace of the feature points with the basis of principal components (when PCA is used) found during the procedure.

Abstract

Generating a crown model using a statistical method (such as k-means clustering, principal component analysis (PCA), or similar statistical methods) can result in a crown model that is missing sharpness details below the threshold of the statistical technique. A method is provided to add back the sharpness to the resulting model by combining a single full-featured example into the algorithms generating the statistical model. The end result is a crown model that is relatively simple to produce and manipulate in real time, yet maintains the anatomical sharpness of a natural tooth.

Abstract

A method for controlling a magnetostrictive ultrasonic transducer of the type used in a magnetostrictive ultrasonic dental scaler includes generating a drive signal for a resonant circuit using a full bridge synchronous class D amplifier. The electrical signal output by the resonant circuit drives an excitation coil that generates an electromagnetic field that causes the magnetostrictive ultrasonic transducer to vibrate. A feedback wire is rendered unnecessary by measuring current and voltage outputs of the resonant circuit and quadrature sampling the measured current and voltage outputs at the same sampling rate as used for the generation of the electrical signal by the resonant circuit. A pulse width modulated signal is generated from the quadrature sampled sensed current and voltage that represents a pulse train approximation of a sine wave of the drive signal for, in turn, being applied to the full bridge synchronous class D amplifier to generate the drive signal for the resonant circuit. Changes in the pulse widths of the pulse train change the amplitude of the drive signal.

Abstract

a rotatable fastening device with an integral torque limiter that comprises an house component and a coupler assembly wherein the coupler assembly comprises means having at least one springy arm and wherein from the instant of its installation within an inner space of the house component, the springy arm tip is biased to be integrated into a recess of a recesses and protrusions array formed in the house component, and wherein the house component is liable to be actuated by providing a rotatable moment on it, around its lengthwise axis in a manner that as long as the actuated torque being actuated is at a level that does not exceed a pre-set threshold level, the springy arm tip remains integrated within a recess of the recesses and protrusions array of the house component and thus - transfers the torque for turning the 10 coupler assembly concurrently with a rotation of the house component, around the longitudinal axis of the house component and thus - fastening a threadable component to which it is connected; and when the actuated torque is at a level that exceeds the preset threshold level, the springy arm is biased into bending so that its tip is moved unto sinking and is extracted from the recess and pushed unto a sliding movement on the surface area of the array, in a manner that the torque transfer is stopped and the continued rotation of the house component around its lengthwise axis does not lead into a parallel rotation of the coupler assembly and therefore, the fastening of the threadable component is stopped.

Abstract

A dental wedge for inserting into the interproximal space between adjacent teeth comprises a first and second sidewall comprised of a shape memory material, including a nickel-titanium alloy, wherein the dental wedge is in a first, resting state when outside of the interproximal space and transforms to a second, operational state when the dental wedge is interested into the interproximal space between adjacent teeth and exposed to a first transformation stimulus, namely exposure to the higher temperature in the interproximal space. The expansion force generated by the dental wedge when in the second, operational stage is sufficient to secure a dental matrix against the tooth being restored and to separate the tooth being restored and adjacent tooth to expand the interproximal space.

Abstract

A method for controlling a dental instrument includes a foot pedal responsive to commands from a user. An operating mode is selectable between normal and boost cycle. A conventional mode is selectable by pressing and holding the foot pedal to a first level to operate in normal mode. The foot pedal operates in a boost mode when the pedal advances to a second level. Maintained mode is selectable by tapping the foot pedal to change modes between idle, normal and boost mode. Each mode is switched by tapping the foot pedal. The pedal switches between the second process and the first process by pressing and holding the foot pedal at the desired level corresponding to normal or boost mode. The pedal switches from the first process to the second process by tapping the foot pedal at the level corresponding to normal or boost.
